Cisco ONS SONET 48-Port DS-3/EC-1 Interface Card

Transcription

1 Data Sheet Cisco ONS SONET 48-Port DS-3/EC-1 Interface Card The Cisco ONS SONET 48-Port DS-3/EC-1 Interface Card provides a cost-effective, high-density DS-3/EC-1 interface solution for hand-offs and aggregation of large numbers of DS-3 and EC-1 circuits between networks. The card s high-density design frees up shelf-assembly slots for additional service-interface types. Product Overview The Cisco ONS SONET 48-Port DS-3/EC-1 Interface Card (Figure 1) provides 48 Telcordia-compliant, GR-499-CORE DS-3 C-Bit or M2/3 framed or unframed interfaces operating at Mbps or GR-253-CORE EC-1 interfaces operating at Mbps received over 75-ohm coaxial cable. The Cisco Transport Controller craft manager supports manual-mode or automode DS-3 frame-format provisioning, simplifying the activation of services. DS-3/EC-1 signals are terminated on one of the Cisco ONS shelf assembly s high-density electrical interface adapter (EIA) panels. The DS-3 interface is used for terminating Mbps plesiosynchronous transport signals within a central office or customer premises. Each DS-3 signal is mapped and transported over a single SONET STS-1 in asynchronous DS-3 mapping mode according to GR-253-CORE encapsulation requirements. The output STS-1 is connected to the Cisco ONS system s cross-connect matrix, allowing the signal to be groomed with other services for transport over a higher-order optical (OC-n) signal. The EC-1 interface is used for terminating Mbps SONET signals, typically from a voice switch found in a central office. Each EC-1 signal is mapped per GR-253-CORE and transported over a single SONET STS-1. The output STS-1 is connected to the Cisco ONS system s cross-connect matrix, allowing the signal to be multiplexed with other VT1.5- or STS-1-based signals for transport over a higher-order optical (OC-n) signal.

2 The 48-port DS-3/EC-1 card supports multiple card-protection options, including 1:0 (unprotected) and 1:N, N 2. It can be provisioned to operate as a working or protection card, reducing spares inventories and their associated cost. The 48-port DS-3/EC-1 card supports circuitlevel interoperability with the existing Cisco ONS port DS-3 and 12-port EC-1 cards. The system supports in-service upgrades, with compatible configurations, from the 12-port DS-3 or EC-1 cards to the 48-port card, allowing the user to increase the number of interfaces supported on a shelf assembly or reduce the number of shelf slots required to terminate a given quantity of DS-3/EC-1 interfaces. To aid with system troubleshooting and fault isolation, the 48-port DS-3/EC-1 card supports near-end and far-end performance-monitoring capabilities at the SONET, DS-3, and EC-1 levels. Loopback support, including near-end and far-end facility (line) and terminal configurations along with far-end activation code (FEAC) support, further simplifies fault-isolation procedures. The card provides three faceplate-mounted status indicators: a red FAIL LED for hardware-level problems; dual color, green/yellow ACTIVE/STANDBY LED to indicate when the card is being used as the active card or a protection card, and a yellow SIGNAL FAIL LED for problems being received on incoming ports. The condition of the card s individual interface ports can be queried using the shelf s liquid crystal display (LCD) panel as well as the browserbased Cisco Transport Controller craft interface. Applications The Cisco ONS Multiservice Provisioning Platform (MSPP), using both low-density and high-density DS-3 and EC-1 cards, supports service provider hub applications requiring the aggregation of large quantities of DS-3 or EC-1 services, and transports them to a large central office for hand-off to core-network switches, voice switches, add/drop multiplexers (ADMs), routers, digital cross-connect systems (DCSs), or other networking equipment (Figure 2).

3 The 48-port DS-3/EC-1 card reduces the number of systems required and their associated footprint, power, and cabling to terminate the DS-3/EC-1 services. The 48-port DS-3/EC-1 card also helps reduce the number of service cards, opening up shelf slots for other services. Figure 3 depicts a Cisco ONS OC-192-based network element delivering 96 DS-3 services, using the 12-port DS-3 card. Figure 4 depicts the additional services that can be delivered over the same footprint when using the 48-port DS-3/EC-1 card. Figure 3 Cisco ONS Configuration with 12-Port DS-3/EC-1 Card Figure 4 Cisco ONS Configuration with 48-Port DS-3/EC-1 Card The high-density DS-3/EC-1 card dramatically increases the overall system flexibility to support the many service types found in the metro networks.
